Copy-paste prompts

Start with these prompts

Create a self-contained quiz app for [QUIZ TOPIC]. It should recommend one result based on answer scoring, explain why the result fits, include a reset button, avoid backend requirements, and work inside a WordPress Custom HTML block.

Quiz QA prompt

Review this quiz logic. Confirm every result can be reached, choices are clear, scoring is not biased by accident, mobile layout works, and the reset button clears the result.
